How to disassemble and recycle solar panel？

As an important part of clean energy, the service life of solar panels is generally around 25 to 30 years. As the solar panels installed earlier gradually reach the end of their service life, how to properly disassemble and recycle these waste solar panels has become an important issue. Disassembly and recycling solar panels requires the removal of aluminum frames, removal of glass, coarse and fine crushing, magnetic separation, air flow separation, and electrostatic separation. Next, I will introduce the disassembly and recycling process of DOING solar panels to you.

1. The whole process of solar panel disassembly and recycling method

whole process of solar panel disassembly and recycling method

a. Removal of aluminum frame: The outermost layer of the solar panel is usually fixed by an aluminum frame. The first step of disassembly is to remove the aluminum frame. DOING disassembly and recycling equipment of solar panels is equipped with a special aluminum frame removal device that can complete this task quickly and efficiently. And DOING frame removal machines can handle different sizes of solar panels on the market.

b. Glass removal: After the aluminum frame is removed, the glass layer of the solar panel needs to be processed next. Henan Dongying's equipment uses advanced glass removal technology to heat the solar panel at high temperature to separate the glass. The separated glass particles are larger and sold at a higher price, which also lays the foundation for subsequent recycling.

c. Coarse crushing stage: A double-axis shearing crusher is used to tear and squeeze the material through staggered blades, crushing large components into particles below 50mm, and separating the residual aluminum frame debris.

d. Fine crushing stage: A hammer crusher is configured for secondary crushing, and the material is crushed to a particle size of 5-10mm using a high-speed rotating hammer head, and the particle size is graded through a vibrating screen.

e. Magnetic separation: A magnetic separator is used to separate ferrous metals (such as welding strips, junction box contacts) from other materials at a magnetic field strength of 5000-8000 Gauss.

f. Airflow sorting: Through high-frequency alternating magnetic fields, eddy currents are induced on the surface of non-ferrous metals to generate repulsive forces to separate conductive materials such as aluminum and copper, with a sorting accuracy of more than 98%.

g. Electrostatic sorting: In a 20-50kV high-voltage electric field, the difference in dielectric constants between the backplane (PET/PVF) and the EVA material is used to separate plastic components through electrode adsorption.

DOING solar panel recycling equipment integrates physical crushing and multi-stage sorting equipment through modular design to achieve full-component material recovery of photovoltaic panels after glass removal. The sorting parameters can be dynamically adjusted to adapt to different types of photovoltaic panels, and the recovery rate can reach more than 98%.
